This response is spot on. I actually wasn't aware that there are differences in understanding z-brush compared to other programs mostly because I'm not that familiar with it. Since the other posts were made, I'm more interested in looking up to see if what was said is true, and if it is I want to know hoe it works in greater detail.
In other cases I post much the same way making a reply that tries to add to the overall conversation even if it doesn't directly reach the person replied to, and in his case I'm not sure that he's a troll. If what you're saying is true he just comes off as being ignorant while trying to sound as if he comes from a place of knowledge. Which is no surprise as this is the internet and, better yet, this is 4chan, and better still, a vaguely tech related board.
